T0 aZZ whom it may concern Be it known that we, HENRY TRUST, a citizenof the United States, and resident of Park Ridge. in the county ofBergen and State of New Jersey, and FRANK M. ASH- LEY, a citizen of theUnited States, and resident of Brooklyn, in the county of Kings andState of New York, have invented certain new and useful Improvements inShredding Machines, of which the following is a specification.

Our invention relates to machines for shredding and comminuting foodstuffs such as potatoes, carrots, cab-bages, etc., and one object of ourinvention is to provide a machine comprising a removable disc havingshredding teeth thereon. A further object is to provide a disc that canbe stamped from thin sheets of metal and the teeth formed in thestamping operation. A further object is to provide a disc havingradially extending corrugations having cut' tions and teeth or cuttersformed with thedisc.

Figure 2 is a vertical sectional view further illustrating theconstruction.

Figure 3 is a perspective view of a portion of the disc.

A indicates a cylindrical receptacle which may be supported in a frame Bfrom its beaded edge A. C indicates a driving-shaft, reduced at itslowerend thus forming a shoulder C. D indicates a spider, and E a disc, thedisc and spider being clamped against the shoulder G by the nut F whichscrews on the lower end of the shaft U and is rotated with the shaft.The disc E is provided with corrugations Iii-H etc., and the cuttingedges located in the sired.

top of the corrugations as illustrated in Figure 3. The food, aftercutting, passes through the openingsJ- JJ, etc., as will be readilyunderstood. The raw potatoes or other such vegetables will be formed instrips of different shape depending on the form of the cutters and maythus give to the strips a fancy appearance when fried or' otherwiseprovided. K indicates a tube the lower end of which is enlarged indiameter as shown at. K and the bottom end contacts with the disc E.Connected to and supported-by the portion K are inclined blades L-Lrespectively which extend to under the edge of M-M respectively of thestrips M to prevent the blades from lifting when in the position shown.N indicates a chuck whichholds the shaft 0 but the tube K is notconnected with, but may abut, the under side of said chuck if de- In"operation, the raw materials such as potatoes are placed in thereceptacle A and the shaft C rotated, carrying the potatoes A under theinclined faces of the blades, thus forcing them against the cutterswhich cut and pass the strips through the openings JJ, etc., from whichthey fall into a receptacle placed below the receptacle A.

Having thus described our invention, we claimas new and desire to secureby Letters Patent: 7
